This pipe 12 is connected tothe crankcase 13 above trap may be made of sufficient size to take the level of the oil therein, such pipe being care of any expansion of water when heated 109 and prevent free water from passing into the i intake manifold. y

Duey to the suction of the engine, the oil vapors developed in the cra-nk case are sucked through the pipe 12, the valve 16, the Y 10 and into the intake manifold. Air isv also sucked in throu h the valve 17.

Thus the cy inders and the engine are charged with the gasified gasoline with itsl proportionate mixture of air with the water vapors, which in the manifold would probably be in the form of steam and with the fwell in an internal combustion engine and oil vapors from the crank case as well as having an additional supplyfof air through the valve 17. By having the water and oil vapor inlets directly opposite the air inlet to the valve 17, these additional charges appear to become intimately mixed. The explosion of i the gasoline or gas causes the vexplosion or burning of the oil vapors and the generation of the steam from the water vapors, this giving an expansion medium which functions results in considerable economy in the amount of gasoline used.

While the use of water vapors in the int take to an internal combustion engine and the use of auxiliary air intakes is old, my arrangement of having a-combination of the water, the oil vapor and the auxiliary or adl ditional air gives an improvement Nin the operation of the internal combustion engine.

It is obvious that the various features comprising my invention may be changed materially structurally from that illustrated, in the drawings and described herein, but such ,Y changes whether in the general construction or specific details would be within the spirit of my invention as set forth in the description, drawings and claim.

Having described my invention, what I claim is In combination with an internal combustion engine having an intake manifold and a radiator, an overflow pipe connected to thel radiator, a water trap having a baflie extendingdownwardly from the top, the overflow pipe being connected to the trap on 'one side of the bafie, an outlet pipe from the trap on" the opposite side ofthe balile, means to drain the trap, means to indicate the liquid level therein, a .Y connection to the intake manif fold, a valved vapor pipe connected to one branch of the Y and connected to the outlet of the trap7 a valved oil vapor pipe connected to the other branch of the Y and to the crank case.

In testimony whereof I have signed my name to this specification.
